gguidone 4b8198fd14 feat(motor_failure_detector): add offline ulog replay tool
Add a host tool that replays a recorded .ulg through the real MotorFailureDetector
and prints the per-motor trip verdict, for validating and tuning the detector
offline (EKF2-replay style: the real library drives recorded data, not a
re-implementation).

Built on ulog_cpp (PX4's C++ ULog library, added as a git submodule and built for
the posix host target only), so it reads ESC current, motor command and arming
state by field name from the log's own format -- one binary replays logs of any
PX4 message version with no rebuild. The feed mirrors the runtime in escCheck:
evaluated only while armed, at the runtime's 10 Hz cadence, with the per-ESC
current-report startup latch and reset-on-disarm. Config comes from the log's
MOTFAIL_* parameters with a built-in calibration fallback, and --set
MOTFAIL_NAME=value overrides any knob for what-if retuning. Because the runtime's
exact 10 Hz sample phase cannot be reconstructed offline, a single pass over the log
drives several detector instances on staggered grid offsets and reports a per-motor
peak band and trip fraction rather than a single phase's verdict, flagging when the
result is phase-dependent.

batch_replay.sh runs the tool over a folder of logs and summarizes each verdict
(OK / FAIL / SKIP) from its exit code.

Off by default so it never enters the firmware build or CI: it is a posix-only,
EXCLUDE_FROM_ALL host executable gated behind the MFD_REPLAY_TOOL cache option.
Build it with:

    cmake -DMFD_REPLAY_TOOL=ON build/px4_sitl_default
    ninja -C build/px4_sitl_default mfd_replay
